BACKGROUND OF THE INVENTION 1. Technical Field

The present invention relates generally to an optical system, and moreparticularly to a compact optical image capturing system for anelectronic device.

2. Description of Related Art

In recent years, with the rise of portable electronic devices havingcamera functionalities, the demand for an optical image capturing systemis raised gradually. The image sensing device of the ordinaryphotographing camera is commonly selected from charge coupled device(CCD) or complementary metal-oxide semiconductor sensor (CMOS Sensor).In addition, as advanced semiconductor manufacturing technology enablesthe minimization of the pixel size of the image sensing device, thedevelopment of the optical image capturing system towards the field ofhigh pixels. Therefore, the requirement for high imaging quality israpidly raised.

The conventional optical system of the portable electronic deviceusually has three or four lenses. However, the optical system is askedto take pictures in a dark environment, in other words, the optical,system is asked to have a large aperture. The conventional opticalsystem could not provide a high optical performance as required.

It is an important issue to increase the amount of light entering thelens. In addition, the modern lens is also asked to have severalcharacters, including high image quality.

BRIEF SUMMARY OF THE INVENTION

The aspect of embodiment of the present disclosure directs to an opticalimage capturing system and an optical image capturing lens which usecombination of refractive powers, convex and concave surfaces offive-piece optical lenses (the convex or concave surface in thedisclosure denotes the geometrical shape of an image-side surface or anobject-side surface of each lens on an optical axis) to increase theamount of incoming light of the optical image capturing system, and toimprove imaging quality for image formation, so as to be applied tominimized electronic products.

In addition, when it comes to certain application of optical imaging,there will be a need to capture image via light sources with wavelengthsin both visible and infrared ranges, an example of this kind ofapplication is IP video surveillance camera, which is equipped with theDay & Night function. The visible spectrum for human vision haswavelengths, ranging from 400 to 700 nm, but the image formed on thecamera sensor includes infrared light, which is invisible to human eyes.Therefore, under certain circumstances, an IR cut filter removable (ICR)is placed before the sensor of the IP video surveillance camera, inorder to ensure that only the light that is visible to human eyes ispicked up by the sensor eventually, so as to enhance the “fidelity” ofthe image. The ICR of the IP video surveillance camera can completelyfilter out the infrared light under daytime mode to avoid color cast;whereas under night mode, it allows infrared light to pass through thelens to enhance the image brightness. Nevertheless, the elements of theICR occupy a significant amount of space and are expensive, which impedeto die design and manufacture of miniaturized surveillance cameras inthe future.

The aspect of embodiment of the present disclosure directs to an opticalimage capturing system and an optical image capturing lens which utilizethe combination of refractive powers, convex surfaces and concavesurfaces of five lenses, as well as the selection of materials thereof,to reduce the difference between the imaging focal length of visiblelight and imaging focal length of infrared light, in order to achievethe near “confocal” effect without the use of ICR elements.

The term and its definition to the lens parameter in the embodiment ofthe present are shown as below for further reference.

The optical image capturing system can be designed and applied tobiometrics, for example, facial recognition. When the embodiment of thepresent disclosure is configured to capture image for facialrecognition, the infrared light can be adopted as the operationwavelength. For a face of about 15 centimeters (cm) wide at a distanceof 25-30 cm, at least 30 horizontal pixels can be formed in thehorizontal direction of an image sensor (pixel size of 1.4 micrometers(μm)). The linear magnification of the infrared light on the image planeis LM, and it meets the following conditions: LM≥0.0003, where LM=(30horizontal pixels)*(1.4 μm pixel size)/(15 cm, width of the photographedobject). Alternatively, the visible light can also be adopted as theoperation wavelength for image recognition. When the visible light isadopted, for a face of about 15 cm wide at a distance of 25-30 cm, atleast 50 horizontal pixels can be formed in the horizontal direction ofan image sensor (pixel size of 1.4 micrometers (μm)).

For any surface of any lens, the profile curve length within theeffective half diameter affects the ability of the surface to correctaberration and differences between optical paths of light in differentfields of view. With longer profile curve length, the ability to correctaberration is better. However, the difficulty of manufacturing increasesas well. Therefore, the profile curve length within the effective halfdiameter of any surface of any lens has to be controlled. The ratiobetween the profile curve length (ARS) within the effective halfdiameter of one surface and the thickness (TP) of the lens, which thesurface belonged to, on the optical axis (i.e., ARS/TP) has to beparticularly controlled.

In the optical image capturing system, the lenses could be made ofplastic or glass. The plastic lenses may reduce the weight and lower thecost of the system, and the glass lenses may control the thermal effectand enlarge the space for arrangement of the refractive power of thesystem. In addition, the opposite surfaces (object-side surface andimage-side surface) of the first to the fifth lenses could be asphericthat can obtain more control parameters to reduce aberration. The numberof aspheric glass lenses could be less than the conventional sphericalglass lenses, which is helpful for reduction of the height of thesystem.

When the lens has a convex surface, which means that the surface isconvex around a position, through which the optical axis passes, andwhen the lens has a concave surface, which means that the surface isconcave around a position, through which the optical axis passes.

The optical image capturing system of the present invention could beapplied in a dynamic focusing, optical system. It is superior in thecorrection of aberration and high imaging quality so that it could beallied in lots of fields.

The optical image capturing system of the present invention couldfurther include a driving module to meet different demands, wherein thedriving module can be coupled with the lenses to move the lenses. Thedriving module can be a voice coil motor (VCM), which is used to movethe lens for focusing, or can be an optical image stabilization (OIS)component, which is used to lower the possibility of having the problemof image blurring which is caused by subtle movements of the lens whileshooting.

To meet different requirements, at least one lens among the first lensto the fifth lens of the optical image capturing system of the presentinvention can be a light filter, which filters out light of wavelengthshorter than 500 nm. Such effect can be achieved by coating on at leastone surface of the lens, or by using materials capable of filtering outshort waves to make the lens.

FIG. 6C shows a tangential fan and a sagittal fan of theoptical image capturing system of the sixth embodiment of the presentapplication, and a transverse aberration diagram at 0.7 field of viewwhen a longest operation wavelength and a shortest operation wavelengthpass through an edge of the aperture. FIG. 6D is a diagram showing thethrough-focus MTF values of the visible light spectrum at the centralfield of view, 0.3 field of view, and 0.7 field of view of the sixthembodiment of the present invention. FIG. 6E is a diagram showing thethrough-focus MTF values of the infrared light spectrum at the centralfield of view, 0.3 field of view, and 0.7 field of view of the sixthembodiment of the present disclosure. In the present embodiment, thelights of any field of view can be further divided into sagittal ray andtangential ray, and the spatial frequency of 55 cycles/mm serves as thebenchmark for assessing the focus shifts and the values of MTF. Theinfrared light with wavelength of 850 nm is adopted.

The first lens 610 has negative refractive power and is made of glass.An object-side surface 612, which faces the object side, is a convexaspheric surface, and an image-side surface 614, which faces the imageside, is a concave aspheric surface.

The second lens 620 has positive refractive power and is made of glass.An object-side surface 622 thereof, which faces the object side, is aconcave aspheric surface, and an image-side surface 624 thereof, whichfaces the image side, is a convex aspheric surface.

The third lens 630 has positive refractive power and is made of glass.An object-side surface 632, which faces the object side, is a convexaspheric surface, and an image-side surface 634, which faces the imageside, is a convex aspheric surface. Each of the object-side surface 632and the image-side surface 634 has an inflection point.

The fourth lens 640 has negative refractive power and is made of glass.An object-side surface 642, which faces the object side, is a concaveaspheric surface, and an image-side surface 644, which faces the imageside, is a concave aspheric surface. The object-side surface 642 has aninflection point and the image-side surface 644 has two inflectionpoints.

The fifth lens 650 has positive refractive power and is made of glass.An object-side surface 652, which faces the object side, is a convexaspheric surface, and an image-side surface 654, which faces the imageside, is a convex aspheric surface. The object-side surface 652 has aninflection point and the image-side surface 654 has two inflectionpoints. It may help to shorten the back focal length to keep small insize. In addition, it may reduce an incident angle of the light of anoff-axis field of view and correct the aberration of the off-axis fieldof view.

The infrared rays filter 670 is made of glass and between the fifth lens650 and the image plane 680. The infrared rays filter 670 gives nocontribution to the focal length of the system.
